Log Message:
Update ruby-timers to 4.1.1.

4.1.1 (2015-08-21)
------------------
* Remove `RubyProf` from Gemfile and a test, due to it providing no substantial \ 
benefit while increasing problems building bundles under Rubinius.

4.1.0 (2015-08-16)
------------------
* Addition of `now_and_every` method; fires block immediately, then sets \ 
recurring timer.
* Includes `now_and_after` method; does the same as above for one-shot timers: \ 
essentially a "two-shot" timer.
